Ahhhh, come on I'm going to patent the information. And make enoungh money to buy an original.. Muhahahaha.
Just kidding...
So this is what I came up with. I have yet to try it so your on your own..
Remove the rear tires, don't forget to jack it up first
Take a flash light and look up where the roll bar comes down. There is a cross member about 2" lower than the seats Hi Tech has pre cut the fiberglass for the Y harness to fit threw. From the back side you can cut the carpet. They have also pre drilled holes for the driver and passenger side to attach the harness. I have not tried this yet, this is just the information I have been supplied. This thread will self destruct in 30 seconds..
Good Luck..
